FRANCIS H. RICHARDS, OF HARTFORD, CONNECTICUT, ASSIGNOR TO THE PRATT d:IVHITNEY COMPANY, OF SAME PLACE.

REGULATOR GRAIN-WEIGHER.

SPECIFICATION forming part of Letters Patent No. 447,354, dated March 3,1891. Application filed Se te ber 10, 1890. Serial No- 364=,574. (Nomodel.)

To all whom, it may concern.-

Be it known that I, FRANCIS H. RICHARDS, a citizen of the United States,residing at Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inRegulator Grain- Neighers, of which the following is a specification.

This invention relates to regulator grainweighers, and has for itsprincipal object to provide improved bucket mechanism and regulatormechanism, whereby the grain is properly handled and the operation ofthe machine reliably controlled.

My present improvements are more especially designed for use ingrain-weighers of relatively large size.

In the drawings accompanying and forming a part of this specification,Figure 1 is a right-hand side elevation of a grain-weigher embodying mypresent improvements. 2 is a front elevation of the machine shown inFig. 1. Fig. 3 is a plan view of the supply-chute and the detailscarried thereon. Fig. at is a plan view of the bucket-latch, showingcertain details operating in connection therewith, and showing a portionof the grain-bucket and of the frame-work in section. Fig. 5 is a planview of the bucketstop, a portion of the bucket carrying said stop beingshown in section. Fig. (3 is a vertical section as seen from the righthand in Fig. 2, and illustrates one step in the opera tion of themachine. Figs. '7, 8, 0, 10, 11, 12, and 13 are sectional views similarto Fig. 6, showing successive steps of the operation of the machine,including the action of the regulator apparatus.

Similar characters designate like parts in all the figures.

In the class of grain-weighers to which my present improvements belongithas been customary to make the regulator-hopperP (when this type orclass of regulator was used) of a size holding more than one completeload of grain, as shown, for instance, in the Letters Patent No.412,724., granted December 10, 1890, to C. H. Cooley and F. H. Richards,wherein said hopper is shown having said relatively large capacity. Bymeans of my present improvements, however, it is made Fig.

practicable to use a regulator or regulatorhopper, as herein shown, ofmuch less capacity than one compartment of the grain-bucket. This objectis attained by means of certain features of my present improvements,hereinafter set forth, whereby the premature discharge of thegrain-bucket is under certain conditions prevented.

The machine shown in the drawings consists of a suitable frame-workcarrying the supply-chute thereon, the scale-beam and its counterpoise,valve mechanism for cutting off the supply of grain, the grain-bucketmech anism, and the regulator mechanism. Some of these features of themachine are taken from and are described in prior Letters Patent, asfollows:

The frame-work for carrying the operative parts of this machine usually,and as shown in the drawings, comprises two suitable side frames oruprights, as 2 and at, which may be held together by the top plate 5(carrying the supply-chute H) and by the bottom plate or bar 3, (hereinshown formed integral with the side frames,) or the side frames may beseparate and held together by suitable tie rods or braces, as shown inthe prior Letters Patent No. 403,988, granted to C. H. Cooley May 28,1889.

The scale-beam B consists of a central shaft 50, two bucketsupportingarms 19 and 21, provided at their outer ends with the usual knife-edges15 and 17, on which to suspend the hangers, a weight-supporting arm 28,oppositely disposed on said shaft relatively to said arms 19 and 21, andhaving a suitable knife-edge 27 on which to suspend the main weight, andbearings which are adapted to rest on the beam-supporting knife-edges 2iand 20, that are carried by the frame-work. This feature of my presentmachine is also described and is claimed in the Letters Patent No.440,740, granted November 18, 1890, to C. H. Cooley and F. H. Richards.

For counterbalancing the bucket mechanism and its load of grain weemploy the improved weight shown in the Letters Patent No. $2,860,granted December 16, 1890, to C. H. Cooley and F. H. Richards, in whichthe main weight W of a mass balancing the unloaded bucket mechanism issuspended from the arm 28 of the scale-beam by the rod 32.

A circular cover 104 is fixed to the top of the main weight, and on thiscover rest the sevequal in weight the load of grain. The cylindricalcover 105 is fitted to slide up and down on the suspension-rod, and ispreferably formed conical at top, as shown, for the purpose of sheddinggrain-dust, &c., falling thereon.

The stop shown herein for limiting the vertical movements of thecounter-weight is of the type shown and described in the Letters PatentNo. 442,720, granted to F. H. Richards December 16, 1890, to whichreference may be had for a more particular description thereof.

In the drawings are shown the bracket 108, the rod 32, and the sleeve121, fixed to said rod by the key 119, said sleeve having the upperstop-collar 122 and the lower stop-collar 123 formed thereon, as shownin said Letters Patent No. 442,720.

The valve mechanism forreducing and for cutting off the flow of grain tothe bucket is actuated from and by the scale-beam. The reducing-valve iscarried by the arms 62 and 64, which are supported on the pivots 61,said valve being furnished with a suitable stop to limit its closingmovement. Said valve closes under the outlet 65 of the chute H somewhatmore than half the width thereof, and is actuated by the valve-lever 69from the valve-actuating arm 71 of the beam B. The construction and modeof operation of this reducing-valve in its preferred form are fully setforth in the aforesaid Letters Patent No. 442,724, to which referencemay be had. Other Well-known kinds or forms of grain-weigher valves may,however, be substituted for said preferred form thereof.

The cut-off valve is carried by the arms 72 and 74, pivoted at 73 to thesupply-chute H. The arm 72 is continued above the pivot 73 and carriesthe cam 68 and some suitable.

weight, as 90. The shiftable actuator 55, which in this case is a smallroller carried by the arm 54,is carried at anormally-fixed point on andrelative to the beam-arm 19, as shown in Fig. 1. This feature of ashiftable actuator is described and claimed in Letters Patent No.442,712, granted tome December 16, 1890, and the construction thereofherein shown is further described and claimed in Letters Patent, No.442,719, granted to me December 16, 1890. The cam, 68 being above thepivot 73 of the cut-off valve and the valvearm being of a short radius,the cam follows the beam in its downward movement, and thus has a moredirect and effective action thereon. This arrangement and combination ofthe several parts permits the use of a valve having a large angularmovement relatively to the beam movement, thereby obtaining a longstroke for the weight 90, that is on the arm of the cut-off valve.

For a more particular description of the operation of the cam-arm on thebeam subsequent to the poising, whereby the weight of said arm is thrownupon the beam for a special purpose, reference is made to the LettersPatent No. 442,722, granted to O. H. Cooley December 16, 1890. In saidLetters Patent No. 442,722 a combination is described wherein the forcethus thrown upon the beam subsequent to the poising is used, as it is inmy present improvements, for disengaging bucketcatches 41 fordischarging the grain-bucket.

As in said Letters Patent No. 442,722, so also in my presentimprovements, said cam-arm may be separate from the cut-0E valve; but

it is deemed preferable that said arm should be fixed on the valve,since by this means the weight of the valve is utilized foroverweighting the beam and the cam is utilized for operating the valve.

That feature of the valve mechanism which comprises the resistance-arm,herein designated by 79, is described and claimed in the Letters PatentNo. 443,569, granted to O. H. Cooley December 30, 1890, to whichreference may be had for a further description thereof. In thatapplication said arm is designated by the numeral 77.

The grain-bucket G is of the well-known double-chambered class, similarto the bucket described in the aforesaid Letters Patent No. 442,724,excepting that in the present instance the bucket-pivots 12 are locatedclose to the lower end of the bucket, so that the angular movement ofthe bucket as it oscillates from side to side on said pivots is reducedto a minimum. Said bucketGis journaled by its said pivots 12 in thelower ends of the hangers 16 and 18, respectively, which are suspendedby V-shaped hearings on the pivots or knife-edges 15 and 17, that aresuitably fixed to the principal arm-s 19 and 21 of the scale-beam B. Theoscillation of the grainbucket withinthe hangers is limited by suit-,able bucket-stops fixed on the bucket, which stops, as herein shown,are designated by 92 and 93, respectively, being projecting lugs formedon a plate 94, (see Figs. 1 and 5 01115 which is suitably afiixed byrivets or otherwise to the end wall 95 of the grain-bucket G. Saidbucket-stops are provided for each of the hangers, as indicated in Fig.2. It will be understood that the particular construction and mode offastening said stops is immaterial to the principal features of mypresent improvements.

For detaining the bucket in its forward and backward positions,respectively, I have shown in this application the bucket-latch ordetent-latch and catches, described and claimed in Letters Patent No.442,715, granted to me December 16, 1890, to which reference may be hadfor amore particular description thereof. Said detent apparatuscomprises a bucket latch or lever 42, which is pivoted at 43 to thehanger, and whose projecting end 45 engages with a bucket-latch stopcarried on the frame-work in a normally-fixed position, which shiftablestop constitutes one feature of my present improvements. Thedctcnt-catch 41 is fitted into the arm 42 and fixed therein by a screw.Said catch a1 engages with the detent catch or stop 10, which issuitably secured to the side of the grainbucket. The rearward end 45 ofthe lever 42 is preferably of a segmental form, being substantiallyconcentric to the bucket-supportingknife-edges when the beam is at thepoising-point, and for the reason set forth in the aforesaid LettersPatent No. 442,715.

At its lower end the grain-bucket is formed with two discliarge'spouts3t and St; for the forward and rearward bucket-chambers, respectively.The inner walls of said spouts are usually provided withadjustably-fixed sheet-metal guards 59 for regulating the slightclearance required between said inner wall and the bucket-closers. In mypresent improvements the bucketeloser is in the nature of a valvearranged to have a swinging movement under and out from under the bucketdischarge-spout. Said bucket-closers are designated by and 76,respectively, and are provided with arms 79 and 80, Fig. 1, which arepivotally supported on studs 77 and 78 fixed in the grain-bucket. Foroperating said closers the upper ends of said closer-arms 79 and 80 areprovided with studs 81 and 82, respectively, to which the links 83 and85 are fitted, the upper ends of said links being connected to the studs86 and 87, which are properly located therefor in the hangers. Inpractice one end of each closer is connected to one hanger and the otherend of each closer to the other hanger, whereby the closerplates 75 and7 6 form, essentially, rock-shafts connected to both hangers, so thatthe swinging movement of the hangers relatively to the bucket iscontrolled and made substantially uniform. By this means sufticientcontrol of the bucket is had without any rigid connection between thehangers for maintaining their parallelism, and at the same time all ofthe connections and pivots may be freely titted so that the bucket mayswing without material frictional resistance. The bucketclosers andtheir connections with the hangers being substantially similar andoppositely disposed, as indicated in Fig. l, the operation of theclosers will, it is thought, be perfectly understood by comparison ofFigs. 1, (5, and 7. The proportions of said parts and their organizationare such that the closer 76 is open, as in Figs. 1 and 6, when thecloser 75 is closed, as shown in said figures. On the bucket swingingfrom its rearward position, as in Fig. 0, to its forward position, as inFig. 7, the closer 75 is opened and the closer 76 is shut, and viceversa. The pivots 77 and 78 of said closers, respectively, are placedsubstantially over the outer edge of the bucketspouts, so that theweight of the grain on said closers tends somewhat to open the closers,and said pivots are placed at such a height above the lower ends of saidspouts, and substantially as shown in Fig. 1, that the angular movementof the closers carries them substantially beyond the bucket-spout whenthe closer is open, at the same time bringing the closer-plate to suchan inclination, substantially as shown, that the grain will run freelyoit therefrom. The closer-spouts are set ata distance below the lowerline of the bucketspout greater in practice than the thickness of thekernels of grain to be weighed by the machine, so that said grain cannotwedge in and clog the machine. To prevent leakage of grain on the innerside of said bucketspouts the aforesaid guard-plates 59 are employed. Atthe ends and outer side of the spout the closer is provided with endwalls 47 and an outer wall TS, (see Fig. 1,) said end walls forming, ineffect, the bases of the closer-arms 79 and 80.

The regulator apparatus comprises the regulator proper, adapted to beoperated by m eansot' the accumulation of grain discharged from thegrain-bucket, shiftable stops controlled by the regulator fordisengaging the bucket-catches, and connections controlling a cutoffvalve from the regulator. The regulator herein shown is theregulator-hopper P described and claimed in Letters Patent of the UnitedStates No. 434,702, granted to O. H. Cooley and F. II. Richards August19, 1890. Said hopper is pivotally supported at 98 and is counter-poisedby the weight 11, carried by an arm 10, fixed to said hopper, which islimited in its movements by suitable stops, as, for instance, pins fixedin the frame-work, as at 399 and T00, Fig. 1. In practice said arm 10 issituated atabout one-fourth of the length of the hopper P from one endof said hopper, being between the counter-weight W and the side columnaof the frame-work. On the rearward side and at the ends of theregulator-hopper are short arms, as 398 and 498, to which are pivotallyconnected the connecting-rods foractuating the aforesaid stops and thevalve-connections.

The bucket-latch stops t6 are carried on the forward ends of levers 395,which are pivoted to the frame-work at 396 and are connected at theirrearward ends to the connecting-rods 397, whose lower ends are connectedto said regulator-hopper arms, as will be understood by comparison ofFigs. 1 and 4, in which this feature of the regulator apparatus is shownin side and plan views, respectively. The oscillating movement of thehopperP on its pivots 9S acts through said rods 397 to swing the lever395 on its said pivot 396, and thus on the rising of the hopper to raisesaid stops t6 into their operative position, (shown in Figs. 1 and 6,)and on the fall of the hopper, as in Fig. 7, to lower said stops intotheir inoperative position. (Shown in Figs. 7, S, 9, l0, and 11.)

Referring again to the valve mechanism and to the cut-off valve 70 andthe shiftable actuator for operating said valve from the scalebeam, itwill be observed that in Figs.

1, 2, and 3 said actuator-arm 54 is connected by a connecting-rod 84,through the intermediate pivot 96, to the arm 97, that is carried 011 astud 58, fixed in the arm 52 of the scalebeam. Said intermediate pivot96 constitutes the middle pivot of a toggle comprising two links 84 and97, which, as shown in Fig. 1, have their three pivots in substantialalignment, the pivot 96 standing, also, substantially in the axis of thescale-beam. For operating said links to shift the actuator from itsoperative to its inoperative position, said pivot is connected by a rod13 to the arm 498 of the regulator-hopper P, as more fully set forth inmy aforesaid Letters Patent No. 442,712.

When the regulator stands in its uppermost position, (shown in Fig. 1,)said connections hold the actuator in its operative position, (alsoshown in Fig. 1,) irrespective of the beam movement. On the descent ofsaid regulator, as when the same is loaded with grain, the pivot 96 israised, thereby shifting the actuator into its inoperative position andclosing the regulator and cut-off valve 70, as in Figs. 7, 8, and 9.

The operation of the machine as regards the Valve mechanism, thebucket-catches, and the regulator-hopper considered by itself and inconnection with the valve mechanism,will be fully understood from theaforesaid Letters Patent and prior applications. The operation of mypresent improvements and of said prior inventions in connectiontherewith are shown in the series of views comprising Fig. 1 and Figs. 6to 13, inclusive. In Fig. 1 the scale-beam stands in its highestposition, (reference being had, of course, to the bucket-supporting armsof said beam,) and the reducing and cut-off valves are both open, whilethe bucket stands in its rearward position, ready to receive grain inthe forward compartment thereof, which is at the left handin said seriesof figures, and the regulator-hopper P is raised, throwing into theiroperative positions the stops 46 and the actuator 55. The machine beingthus conditioned and the grain being supplied to the chute H, asindicated by the stippling in Fig. 6, the grain flows into the forwardcompartment, as shown in Fig. 6, until themajor part of the load isreceived and the reducing-valve is closed, as there shown, allowing thedrip cl to flow into the bucket. This continues until the load iscompleted,when the beam descends and the cut-ofi valve 70 is closed, asin Fig. 7. The descending bucket in the meantime brings the levers 42against the stops 46 (while the stops are in the position shown in Fig.6) and disengages the bucket-catches, whereupon thebucket swings over,by reason of its load, into the position shown in Fig. 7, therebyopening the closer 75 76, as there shown. On this movement of the bucketthe grain flows out, as indicated in Fig. 7, into the hopper P, therebyoverloading said hopper and carrying the same into its lowermostposition, as there shown.

and closing the closer If it shall happen that the grain is taken awayrapidly, the accumulation in the hopper P will be insufficient to carrydown said hopper, which will remain raised, as in Fig. i 6, and theoperation of the machine will continue; but if the discharge-outlet ofthehopper P is somewhat obstructed (as is supposed to be the case inFigs. 7, 8, 9, and 10) then the accumulation in said hopper P carriesdown the same and throws the stops 46 into their inoperative positionand at the same time shifts the actuator 55 into its inoperativeposition, whereby the valve 7 O is continued closed and the stops 46 arecontinued down. If now the grain is slowly discharged from the hopper P,(as is supposed to be doing in Fig. 8,)

the load in the forward bucket-compartment is gradually lowered, (asindicated by comparison of Figs. 7 and 8,) so thatthe counterpoise Wraises the bucket, opens the valve 60, and thus permits grain to flow(as indicated by the stream 6, Fig.8) into the rear compartment of thebucket, thus gradually increasing the total bucket-load (part of saidload being in each compartment) until, as shown in Fig. 9,

the scale-beam is carried down by said combined partial loads and thereducing-valve thereby closed, the gradual discharge of grain from thehopper P continuing as before. Finally the load in the forwardbucket-compartment will be entirely discharged, as in Fig. 10, thusagain allowing the beam to partially rise and partially open the valve60, whereby more grain is allowed to flow, as at e, into the rearwardcompartment until thiscompartment has received the major part of itsload, as indicated in Fig. 11, and thus again close said reducing-valve60, when the machine stands idle, as indicated in said Fig. 11. Saidgradual discharge from the hopper P still continuing, the grain is firstlowered in said hopper from the full load (shown in Fig. 10) to thepartial load, (shown in Fig. 11,) and later to the substantially emptycondition in Fig. 12, wherein the hopperPis shown as having been raisedto its former position.

(Shown in Figs. land 6.) By said movement andby means of the rod 13above described, the cut-01f valve is opened, and the dripcolumn d flowsinto the rearward bucketcompartment for completing the secondbucket-load. When this second load is thus regularly completed, saidhopper being now empty and the stops 46 in their operative position, thebucket is carried down, as in the first instance, until the levers 42strike said stops46,and thus unlock the bucket, which is carried by itsload from its forward position in Fig. 12 to'its rearward position inFig. 13, thereby closing the empty forward compartment and opening thecloser 76 of the rearward compartment,which discharges the rearward loadand allows the scale-beam to rise, as in Fig. 1, ready for receiving athird bucket-load in the forward compartment, as in Fig. 6. Thus bymeans of my present improvements the complete cycle of loading and.iegnlating operations goes on without at any time the bucket beingempty of graimeXcept, possibly, when the regulator-hopper is veryrapidly discharged. In practice the scalebeam is not carried down, atthe stage indicated in Fig. 9, quite as far as there indicated, sincethe gradual closure of the reducing-valve provided for by the reducingcamarm (it), as described in the aforesaid Letters Patent No. 412,724,co-operates with the gradual discharge of the grain to increase the loadin the rearward compartment gradually as the load in the forwardcompartment is reduced, thus partially opening the reducingyalve andavoiding a fulldescent of the scalebeam. In practice, however, it isdeemed essential, as a matter of safety, that the stops 46 shall bethrown down by the descent of the hopper I suiiiciently to beinoperative for detaching the bucket-latches, even if the bucket shoulddescend to thelowest point in its stroke.

It will be understood that my invention is not limited to the use of amultiplicity of bucket or detent-latches in the bucket mechanism, or ofthe shift-able bucket-latch stops, since in some cases it is sui'ficientto use one detent-latch located at one end of the bucket and operatingin connection with one of the bucket-supporting hangers, and to use foractuating said single latch only one shiftable bucket-latch stop carriedby the frame-work and operatively connected to the regulator.

llaving thus described my invention, I claim- 1. In a grain-weigher, thecombination, with a rising and falling grain-bucket suspended from thescale-beam of the grain-weigher and having a bucket-latch fordischarging the load, of a regulator located and supported for operationby the discharged grain, and a shiftable bucket-latch stop carried bythe frame-work and operatively connected to the regulator, whereby saidstop is shifted into an inoperati\*e position on the working stroke ofthe regulator.
